In the wake of the recommendations of the Federal Initiative to Address HIV/AIDS in Canada, this study will provide data on the effectiveness of different forms of preventive counseling tailored for use in conjunction with rapid HIV testing. If MIC proves to be effective, the training and clinical supervision offered to intervention staff as well as the tools and quality control procedures developed during the implementation of this approach to counseling will be made available in other settings where testing is offered. Important lessons may also be learned with regards to the organization of services and the benefits and challenges associated with the implementation of this type of HIV prevention infrastructure. Ultimately, this study will contribute to efforts to more effectively combat the HIV epidemic amongst MSM in Canada and reduce the direct and indirect costs associated with HIV in these communities.
